IMPROVEMENT IN HARVESTER-RAKES.v

Specification forming part of Letters Patent No. 123,701, dated February13, 1872.

To all whom t may concern:

Be it known that I, WILLIAM R. G. HUMPH- REY, of Chillicothe, in thecounty of Livingston and State of Missouri, have invented a new anduseful Improvement in Harvesters,

of which the following is a specification, reference being had to theaccompanying drawmg.

Nat/nre and Object ofthe Invention.

The invention relates to an improvement in raking attachments forharvesters; the object of the invention being to rake the platform of aharvester from one end to the other by means of an arm provided with arake and operated by a crank-axle, as hereinafter specified anddescribed.

.Description of the Accompanying Drawing.

Figure l is a plan view'of a device embodying the elements of theinvention. Fig. 2 is a side elevation of same. Fig. 3 is a verticalcentral longitudinal section of same. Fig. 4 is a perspective view ofthe rake. Fig. 5 is a plan view of the arm B.

General Description.

A is a frame, the front part of which is rectangular, the rear portionbeing V-shaped. At the apex of the rear frame is pivoted the arm B, thefront end of which is provided with a vertical opening forming a fork.rI he ends of the sides of the arm B are reduced to such an wheel isattached to a vertical spindle secured to the rectangular slide e, whichis attached to the supporting plate, and operates between the parallelguides D D', which are secured at each end to the sides of the frame A,about midway between the upper and lower edge thereof, an aperture beingin the frame on the sidefopposite the drivers seat, provided to receivethe end of the slide e. In the present instance the arm B is providedwith the friction-roller n, revolving upon the axle Z, which is properlyattached to the under Side of the arm, so that the friction-wheelrotates upon the curved traveling-door D; but the arm B may also be usedwithout the friction-roller o r shaft, or the traveling-floor D. Therake-head o is provided with the teeth b, which are firmly Set in saidhead, which is so constructed as to oscillate freely in bearings orstaples attached to the supporting plate d. The teeth b may have theirpoints inclined forward so that they will gravitate into a horizontalposition below the bars E, which form the platform when relieved fromsupport above the said bars, or these teeth may be straight. Near eachextremity of the rake-head is a curved staple or pin, g, so arrangedthat when they strike the frame they will rotateN the rakehead,elevating the teeth into a vertical position. The link h connects thearm B, and vertical axle k being journaled at one end in an aperture inthe arm B, and at the other end in an aperture in the end of the lowerarm of the axle 7c, which axle is provided at its upper extremity with asecond arm, l, which stands in the relation of a right angle both to theaxle hand to the arm i. rlhe axle 7c is of sufflcient height to soelevate the arm Z as that the rod m is so raised above the horizontalplane of the platform that the gavel may be delivered over the sidewithout hindrance. The axle la oscillates in a vertical frame rigidlysecured to the frame A. lhe axle 7c is connected with the arm n by meansof the rod in, one end of which is bent and works in an aperture nearthe arm Z, the other operating similarly in an aperture in the upperextremity of the arm n, which is rigidly secured to the horizontal axleF that oscillates in bearings fastened to the frame of the rea-perimmediately in front of and below the drivers seat, which axle isprovided with an operating lever and stirrups within easy reach of thedriver-s hands or feet, and whereby he may operate the device.

Operation.

The device being attached to a reaper, thev rectangular part of theframe A lis immediately in rear of the cutter-bar. The lever G beingretracted throws the rake against that side of the frame opposite thedrivers seat, thereby elevating the teeth g, and the reaper is thenstarted. The reel throws the cut grain upon the platform. When asufficient quantity is thus deposited to form a sheaf the lever G isprojected, which moves the rakefhead, the teeth of -Which carry thegrain across the platform over the side of the frame in rear of thedrivers seat. The lever is then retracted, the teeth of the rakefalling,` into a horizontal position, and so passing below the platformto the other side of the frame.

The same operations may be performed by using the stirrnps Z in asimilar manner.

The rake may be constructed so as to stand above the platform.

Claims. I claim as my invention and desire to secure by LettersPatent- 1. The forked arm B, having the ends of its prongs beveled tothrow the pin on the rakehead directly against the delivery side of theframe, substantially as shown and described.

2. The forked arm B, as described, in combination with the rake,consisting of the rakehead c, teeth b, staples g, supporting plate 11,.
